Original issue's description:
> Make TextMatchMarkers constructible in single step
>
> Currently, we only construct instances of TextMatchMarker (previously
> RenderedDocumentMarker) inside TextMatchMarkerListImpl, by calling
> TextMatchMarker::Create() on an instance of DocumentMarker. This CL changes this
> so callers directly construct instances of TextMatchMarker. This sets us up to
> eventually move the storage and accessor methods for whether or not the marker
> is active out of DocumentMarker and into TextMatchMarker.
